SPECIFIC'ATION forming part of Letters Patent No.4=63,321 dated November 17, 1891. Applicaion filecl J annary 13, 1891. Serial N0. 377,640. (Model) T0 all whom it may concern:

Be i known ha I, SEYMOUR ROGERS, of Beaver Falls, in l1e counry of Beaver and Stae of Pennsylvania, haveinvened eertain new and useful Improvements in Vovem \Vire Mais, of whieh he following is a full, elea1, anal exae eseription.

The objeetof my invenion iS o prodnce a woven-wire fabric eonsisting of a series 0f primary eoils of spiral wire iniercoilecl npon a parallel plane ancl a secondary Se1ies of Spi- 1al wires intereoiled witl1 eael1 ol1er upon a parallel plane, ancl with the primary series at a right angle With iheir plane t0 loek tl1e free encls of he several eoils of both series upon the outer eclges 0f the ma in such manneras shall leave tl1e fabrio flexible yet fi1m, ancl to eonstrue upon Such a ma a border 01 eclge whieh Shall be simple, eifeetive, ancl eoonomieal.

In the aoeompanying drawings, Figure 1 is a view of four primary eoils A B O D intereoilecl upon a parallel plane. Fig. 2 is a view of fou1 secondary eoils ab c clinereoilecl Willi eaol1 oher and Wih the primaries A B C D a a rigl1 angle Wih saicl primary eoils A B O D. Fig. is a view of l1e edge of a ma const-rnoted in l1is manner and Wil1 l1e en(ls of the ajuing spirals fastenecl by hancl in tl1e manner hereofo1e praeieed. Fig. 4 is a view of tl1e edge of a ma fasenecl in my improved mocle. Fig. 5 is a view of l1e Same a 1ight angle to Fig. 4; and Fig. 6 iS an elge view of l1e same, sl1owing he 1elaion of tl1e convoluions o1 riclges h h o eaeh other and he relaion of 1;l1e Spiral border to l1e ma.

The leters A B O D denoe the primary eoils, and tl1e letters a b c d l1e Seeondary coils, of a Wire-woven ma, and there may loe any approvecl number of eoils in eael1 series, each eoil being macle 0f wire in the fo1m of an elongatecl Spital ancl inereoiled Wih he others in the manner eommon in tl1e ar of 1naking mats 0f his cleseription.

Hereofore, a ma of the prescribed size having been eonstrnotecl, the operative would seize the projecing ajuing encls' of a pri- 1nary coil, aS D, and of a seeondary eoil, as a d, en hem oll to a proper length and bend' them upon eaol1 oher, as shown a J, Fig. 3.

AS this operatiou l1as been performed, he proeess is tedious and expensive, l1ere is a 1aok of uniformity in he tension under whieh each Spiral wire end is ben ancl ma(le fast, and Elle proclue is a ma no nniformly flexible, ancl from l1e unequal tension of iS o0il liable 130 buekle er wis.

By my improvemen the fabric may be woven of any desired lengh ancl may be finished as one ma 01 divided into several. In

either ease a broad blun die, as a K, Fig. 5,

is pressedalong the eoil H and erushes hat coil clown,as shown in Figs. 4ancl 5. Bythis means 11e terminal eoil of eacl1 seeondary spiral is flattenecl down o a poin where i embraees the end of the nex seeondary Spi- V 1al 011 he one sicle ancl of tl1e next primary. Spiral on its ot-l1er side. A broad shear-blade operaing in l1e Same direotion ashe blun dies shears off hese projeoting ends, leaving a ma with a uniformly-lookecl edge having a uniform tension upon eaeh Spiral number of boh primary ancl seoondary series, and cousequenly uniform flexibility.

lt Will loe Seen loy reference o Figs. 3 and 4 tl1at l1e old proeess ormethod neeessiaecl he bending of ea oh end separately and hat uniformity mus be aeeidenal, tha the 1110- ion of he spirals waslimitecl by he elosemess of the bends of thei r ajuting ende ancl that a strain was brougl1t npon the edge of such a ma encling to bue kle tl1e fabrie to cause it o lie wavecl 01' nnevenly, and to rencler i Siif ancl neu-flexible 150 a grea exifen. It Will be noted in he edge illustraecl in Fig. 4 hat l1e ension is uniform and the ajuting ende 0f the several spirals are free to adjus hemselves o he n1oion cansecl by tension 0f l1e spirals or rolling up of tl1e fabrie, while they easily allow tl1e ma to lie level upon the fioor 01' t0 assume he contour of l1e surface upon Wl1i0h it 1's plaeed. A the Same time i Will be evident tl1a l1e spirals are effeciively locked agains displaeemen in any direetion l1at he ernshed 5 Spiral c, for instanee, prevents sicle motion a onee of l1e spirals d ancl b, and is a he Same time helcl in plaoe by those spirals.

Vhere it is desirable to furnislx such mas wih smooh borclers, a spiral of wire is woven in the usual manner of the a1t withiu tl1e edge left by this proeess of finishing. 111 will be seen that an edge made in this way furnishes a uniform series f convolutions for the admission of such a spiral, and that this uniformity Will permit the mat o0 lie level upon tl1e floor without tl1e twisting 01 erooking incident t0 a mat having its eclge twisted er loeked by band in the nsual way. 113 Will be seen, further, that the compression of the coil H may be made to such a degree as t0 raise the mal; from the floor when the borderspiral is woven into place 01 to depress nhe border-spiral below the level of the ridges h h, as desired. The crushing and shea1ing of the' edges is best accomplishecl by means of a press and shear of ordinary construetion, in Whieh the die am]. knife are operated at an angle With the plane 0f the fabrie body, as shown at K, Fig. 5; but it Will be obvious that these stepsin the processmay be effeetecl by any device in which the eompression 01. the coil H by the die K or its equivalent may be regulated and the shearing of the ends L effeeted.

When the edge of a mat has been locked by hand in Ehe old methods, obere exists a laek of uniformity in the spaces left by the loeked ends 0f wire, and the operative is coil t0 the irregulariiies caused by the unequal hand-loeking and. to str eteh 01 compress the leading-eoil 't0 meet Ehe eontinually changing spaces in the' hand-loeked edge. The result is that the mat, already stiff and non-flexible from the unequal tension of its edge, is renclerecl more so by the additional tension of thev border-coil within and upon this hand-loeked eclge.

By my improvement tl1e edge is a series 0f flexible loops of exaetly sirnilar eontour and size, and a border-coil of the proper piteh runs eontinuously and easily from ehe inaehine upon these loops, am]. forms witl1 them a flexible mal; in Which the tension is equal upon eaeh mennber of the mal; and upon each coil of the border.

By tl1e Word ajuting used in this speeifieation and in the elaims is meant the adjoining and crossing of the ends of the spil. In the manufaeture of a wire-woven fabric of the elass deseribed, the herein-deseribecl method of locking o1 tying the edge of such fabrie by first crushing er eompressingthe terminal coils 0E the secondary spirals so that they are caused t-o embraee the ends of the ajuting primary spirals, and then shearing ofi the projeeting ends uniformly, whereby each spiral is caused. to

retain in plaee its neighboring spiral upon either side, and is itself retained by them and the locked ende a1e permitted to slide orplay, thereby retaining he flexibility of the fabric, as shown and clescribed.

2. A wire-woveu mateonsisting, esseintially, 0f a parallel series 0f primary intereoiled spirals 0f wire, and a secondary series of like Spirale iner eoiled with eaeh other in a par all e1 plane and with the primary series at a right angle t0 their parallelism, the two series being locked together by the crushing 01:

the terminal coil of eaeh secondary spiral upon the tenninal coil 0f each primary ajuting spiral and. the shearing of the projeeting ends, whereby the locked ends are permitted unifnrmly to slide 01' play, and the flexibilityof the mal; is retained, as shown and described.

3. The eombination, with ehe herein-deseribed erushed and sheared edge of a wirewoven ma's 0f the dass deseribed, 0f a spirallyeoiled border 0f wire intereoiled with and upon such erushed and sheared edge, as shown and deseribed.

4. As a new artiele 0f mauuf-aeture, a wire mat, t-he edge of which is crushed and sheared and provided witl1 a spiral coiled. border of wire intereoiled With and upon such crushed and sheared edge, as shown and deseribed.
